Steps to reproduce the defect:

1. Open the Ajax sample in IE7.
2. Click on the Insert Table icon to dispaly the table properties dialog.
3. Enter the number 1001 (or greater) into the Cell Spacing (or Cell Padding or Border Size) text field & click OK.
4. See that the table is displayed without the Cell Spacing attribute value applied to it.
5. Right click on the table and choose Table Properties from the context menu to display the Table dialog.
6. Change the value of the Cell Spacing textfield from 1001 to the number 10 & click OK.
7. See that a table is displayed with the correct Cell Spacing attribute value applied.
8. Right click on the table and choose Table Properties from the context menu to display the Table dialog.

Expected: The value in the Cell Spacing textfield is 10.

Actual: The value in the Cell Spacing textfield is 1001.
